I flat out *guessed* at a lot of the PC game questions, as the last PC game I bought was Leather Goddesses of Phobos.

I have to note that I bought it so I could use TRS-80 version of that to make the PC version of Hitchhiker's Guide to the Galaxy work on my TRS-80 (I can explain how this works if you are intersted in that level of true geekery)

I also had to guess on the 3rd edition AD&D stuff. I quit buying stuff around the time of the second edition.
